Installation
Mount the pump to suit the type of installation planned. Pump dimensions and mounting hole layout are shown on page 14.
CAUTION
The hydraulic supply system must be kept clean at all times to avoid damage to the motor and hydraulic power supply. Blow out all hydraulic lines with air and flush thoroughly with compatible solvent before connecting the lines to the motor.
Always plug the hydraulic inlets, outlets, and lines when disconnecting them for any reason, to avoid introducing dirt and other contaminants into the sys- tem.
Filters
Be sure that your hydraulic power supply is equipped with a suction filter to the hydraulic pump and a system return line filter of 10 micron size.
Carefully follow the manufacturer’s recommendations on reservoir and filter cleaning, and periodic changes of hydraulic fluid. Use only
Hydraulic Lines
Connect a 3/4 in. minimum ID hydraulic supply line (L) to the 3.4 npt inlet of the hydraulic motor. See the Typical Installation on page 7. Connect a 1 in. mini- mum ID return line (D) to the 1” npt return port on the hydraulic motor.
On the hydraulic supply side (C), install the following accessories shown in Fig. 2, using adapters as neces- sary.
DA shutoff valve (E) isolates the pump for service.
DA fluid pressure gauge (F) to monitor hydraulic oil pressure to the motor and to avoid overpressurizing the motor or displacement pump, and a pressure- and
DA pressure reducing valve (H), with a drain line (K) running directly to the hydraulic return line (D).
DAn accumulator (J) to reduce the hammering effect caused by the motor reversing direction.
DA shutoff valve (E) isolates the pump for service.
CAUTION
Do not exceed 10 gpm (37.8 liter/minute) volume to avoid pump stalling.
Drip Pan
The hydraulic motor is equipped with a drip pan to collect any leakage that might occur. connect a 1/4 in. ID drain hose (Q) to the barbed hose fitting on the drip pan.
Drain Valve
Install a high pressure fluid drain valve (B) near the pump fluid outlet to relieve fluid pressure in the dis- placement pump and hose during shutdown.
WARNING
The fluid drain valve (B) is required in your system to help reduce the risk of serious bodily injury, including fluid injection and splashing in the eyes or on the skin if you are adjusting or repairing any part of the system. Triggering the gun to relieve pres- sure may not be sufficient.
Fluid Supply Lines
Connect a grounded fluid supply line to the
If you are pumping through a long hose, or if the fluid being pumped is compressible, giving an accumulator effect, install a check valve at the pump outlet. Be sure that the check valve selected is capable of handling the flow and pressure developed in your system.
